"f igure fiiliustratesa similar An object ofthe"invention:isftofprovide a clamping means having a fle k i bleelement which is caused to embrace the pipe -sections, the saiddevicebeing provided with rneans for tensioning 1051 a the pipeembracing element so that theis aid pipe" c'fnovelrneans are ng'means iswound different positions sections are, held assembled, providedbywhichth tensiom on a drum or shaft and'held at A further object of theinvention is to provide a pipe holding instrumentality and to associateit with a manually rotated shaft on which the tensioning member iswound; the said shaft being also provided with ratchet wheels engaged bya pawl, which pawl is under tension of a spring that automaticallycauses the engagement of the pawl with the said ratchet teeth.

It is furthermore an object to provide a housing for the tensioningmeans, the ratchet of which is accessible through the housing so that itmay be manipulated after the device is fully assembled.

It is a further object of this invention to provide a pipe holder of thecharacter indicated having a plate adjustable on the frame, the saidframe having graduations thereon to indicate the width of a pipe towhich the device is adapted for use, the said plate having an anchoragefor a flexible pipe embracing element, which element is wound on a shaftfor regulating the tension thereof on the pipe sections which areembraced by the work holder.

A still further object of the invention is to produce a work holder ofthe character indicated which is efficient and satisfactory in use andcomparatively inexpensive to manufacture and maintain.

With the foregoing and other objects in view, the invention consists inthe details of construction, and in the arrangement and combination ofparts to be hereinafter more fully set forth and claimed.

In describing the invention in detail, reference will be had to theaccompanying drawings forming part of this application, wherein likecharacters denote corresponding parts in the several views, and inwhich: f,

Injtesedrawings, i denotes a frame having iiies- 2-, on a rate a rs sueablezwfrnere is a fflaj'nge dhaving gradiiatieiwnumbers thereon any of thenumbers of the graduations so that proper positioning of the plate maybe attained. The frame has a slot 6 therein in which a bolt I isslidable, the said bolt being engaged by nuts, such as 8, above theplate and below the frame, so that by adjustment of the bolt the plateis clamped in different positions of adjustment. The outer end of theplate has a lug 9, for a purpose to be presently described.

The sides 2 of the frame are cut away. as at ID, to form bearings for ashaft II and said shaft being rotatable in the bearings has a flexibleclamping element l2 wound thereon. The said clamping element is causedto embrace pipe sections l3 and I4 in the manner shown in Figure 2, andwhen the shaft is rotated, the clamping element is wound on the shaft sothat the tension of the clamping element is caused to hold the pipesections assembled; it being understood that the end of the clampingelement has a ring or yoke is which is engaged by the 111g 9 so thatwhen the clamping element is wound on the shaft it will be retainedassembled with the pipe sections as shown in Figure 2.

Ratchet wheels l6 and I! are also mounted on the shaft l I, and theteeth of these ratchet wheels are engaged by a detent or pawl l8 whichis mounted on a pivot IQ of the frame member carried by brackets, suchas Illa. The pawl bracket shaft may be rotated and when the propertension has been attained, the pawl will hold the parts in theiradjusted positions. Preferably, the shaft is rotated by a knob or handle22 secured to the shaft and this knob or handle is externally of ahousin which comprises the two sections 23 and 24, the former beingsuperimposed on flanges, such as 25, of the frame, whereas the latter isunderslung on the frame, and these two housing sections are heldassembled on the frame by fastenings, such as bolts, 26, as thoseskilled in the art will understand.

The housing section 23 has an opening-through which the outer end of thepawl is accessible, or through which it may project so that it may bepressed by an operator for the purpose of disengaging the pawl from theratchet teeth. It will thus be seen that the operating parts of thedevice are accessible from points externally of the housing and thatadjustments may be made to accommodate pipes of difierent sizes ordimenslons.

I claim:

1. A pipe clamp comprising a frame, a member slidable on a portion ofthe frame, means for holding the said member in different positions ofadjustment, a lug on the outer end of said member, a flexible pipeembracing element having a connection for anchorage to the lug, a shafton which the pipe embracing element is wound for regulating its tensionon the pipe sections, means for holding the shaft in different positionsof adjustment, ahousing for the shaft and said means, and a handoperated element on the shaft externally of the housing for rotatin saidshaft.

2. A pipe clamp comprising a frame, a member slidable on a portion ofthe frame, means for holding the said member in different positions ofadjustment, a lug on the outer end of said member, a flexible pipeembracing element having a connection for anchorage to the lug, a shafton which the pipe embracing element is wound for regulating its tensionon the pipe sections, means for holding the shaft in different positionsof adjustment comprisin ratchet wheels on said shaft. a spring presseddetent engaging the ratchet teeth for holding the shaft at differentpositions of adjustment, a housing for the shaftand parts associatedtherewith, and a hand operated element on the shaft externally of thehousing for rotating said shaft.

3. A pipe clamp comprising a frame, a member slidable on a portion ofthe frame, means for holding the said member in different positions ofadjustment, a lug on the outer end of said member, a flexible pipeembracing element having a connection for anchorage to the lug, a shafton which the pipe embracing element is wound for regulating its tensionon the pipe sections, means for holding the shaft in different positionsof adjustment, and a hand operated element on the shaft for rotatingsaid shaft.
